1702  Other / MultiBit / Re: How secure is password generation in MultiBit HD? on: May 06, 2016, 09:34:36 PM
So, currently I do not worry about the security about my Bitcoins?

I dont know what you worry about.

In your first sentence you state that it is not secure.

No. I say "No, its not" to your "Is it not possible to try all combination of the words in order to get the right pass?".

In the last sentence you state that it is secure by now. Confuseingly.

I just downloaded MultiBit HD. By now, I have used Multibit Classic. I am wondering how secure the 12 words passphrase of MultiBit HD is?
Acutally, the group of words are all known. Is it not possible to try all combination of the words in order to get the right pass? Something like a bruteforce attack.

No its not. The symbols for your private keys are well known as well (1,0 if encoded binary, [a-f0-9] if encoded in hex). Think of the words like a different set of symbols. They still represent a 128-bit (IIRC) number, which is impossible to brute force with currently available technology. It may be possible in the distant future, but for now there are no signs that it ever will be.

Your assumption that because the symbols are known its less secure makes no sense.

Can you tell me how to sign an address via Bread Wallet ?

The last time I had access to an iOS device it was not possible.

We need to mail a link of this info to Craig Wright, apparently Satoshi has forgotten how to do it.   Roll Eyes

Feel free to send him a copy.

Since we are talking about very old keys, should be enough to send the bitcoin core part Wink
1704  Bitcoin / Development & Technical Discussion / Re: Vanitygen: Vanity bitcoin address generator/miner [v0.22] on: May 06, 2016, 08:30:27 PM
any way to generate a litecoin vanity adress with this version of vanitygen ?
 i know there's  possibility to do it with another forked version (from dasher): https://github.com/dasher/vanitygen , but i want to know if we can generate it with samr7  version.
Thanx in advance

If you go to http://cryptolife.net/upwg/ you can work out what number corresponds to a given coin, then use the

Code:
-X

flag for what ever coin you want to generate

eg SXC

Code:
oclvanitygen64 -X 62 -o answer.txt -D nnn Ryan

Ryan9u6ZqjaeEfdauSMKyM8Pv44Jn82jiF

eg LTC

Code:
oclvanitygen64 -X 48 -o answer.txt -D nnn Lake

LakewBLjhjYF6ufiqGDAj3K336t5A41oLN

(does that mean I have the first known Vanity Wallet Address for LiteCoin?)

I thought it was a bit OT, but then I noticed a lot of verification requests also in this thread.

I think we should to let people try here. Its not the same as staking an address. I see it more as the opportunity of a playground. Posting a signed message here that someone else can verify also shows me that people are actually able to sign message, while a "thx, learned it" does not and often feels like a spam post just to increase the counter by one. Thanks for the verification btw.

So you would pay me 0.01 BTC for allowing you to push an arbitrary TX that has ~7kbyte in size to the network?
Well as you can see it only has one input and a size of 7176, so not just any transaction with 7KB but a transactoin exactly like the stated one (of course the address will be different).Also there will be one more input, an input from my normal address. Yes I would pay 0.01BTC for that.

Now I understand even less what you want. If you want a TX exactly like the one you linked, there is an obvious source[1]. You want to add one more input, is this supposed to be some sort of CoinJoin? Maybe you can list a clear set of requirements? Im pretty sure someone will make it for a coffee worth of bitcoin.

1708  Economy / Services / Re: Create me a transaction [0.01BTC reward] on: May 04, 2016, 11:18:25 AM
If someone else makes the transaction for you then it's not your transaction it's theirs, the most you would get out of it is showing a 7kb transaction going to your address.
So?I'll get to have the raw tx and I'll get to push it, that's the terms. You can call it theirs tx or mine, I don't care, do you?

So you would pay me 0.01 BTC for allowing you to push an arbitrary TX that has ~7kbyte in size to the network?

Hi Jet Cash,

you are right. I did leave a lot of things out. For different reasons. Chromebooks aren't a big thing in Austria and I didn't know them until some days ago. Leaving out the nodes is of course my fault. However, as I am researching a very particular effect it should not be a huge problem. Too few participants are though  Wink

Didnt finish it, you ask too many personal informations. Im pretty sure with some digging the answers can be used to identify at least some forum members that have answered your survey honestly.

So you think that if he posts his Bitcoin address online someone will show up at his house and kill him for it?  Well okay, thanks for the advice.

If they know there's a big pay off? Yes, criminals will use that information.

Exactly. Your setup might not be secure, it might just be that no one bothered to try and break it. The larger the amount of BTC you knowingly own the higher the chance that you get targeted.

Beeing trageted must not mean that someone comes to your door and try a wrench decryption[1]. It can mean a variety of things, but overall its not bad advice to

#1 dont keep all your coins on a single address (or even wallet)
#2 dont tell the world how much you own

You might check the first pages of this thread. There were screenshots posted though he changed some things so I don't know if it is possible to find him with that details anymore at all.

The nickname (mf-jones) can easily be changed. I know that some people know his steam ID though. I dont see how this can help though, blocking someone on steam is easy and you cant force to be matched in CSGO with someone outside of your friendlist.

Hi Guys,

Unfortunately I have had 5 bitcoins stolen from my wallet. I have a bitcoin core wallet which is encrypted and hardly ever use.

I have full anti virus software on my computer and in my mind that is pretty safe. It looks like the thief tested my wallet with 2 small transactions and then took the other 4.6 bitcoins.

Anti-virus software can not protect you from current malware. It can -at best- protect you from old malware that has been around for a while.

Obviously I am annoyed at this and want to protect the rest. This was back in November and I haven't been about since then or even used my wallet or updated it. {I have only just checked it and am updating the walled transactions now}


Please can I have advice on how to go about fully protecting this from happening again? I am not that tech savvy per say so an idiot's guide would be helpful.

Thanks in advance.

Russ

There is no 100% protection, the closest you can get is probably a hardware wallet.

Btw, where do you keep the rest? I would assume that the wallet is empty if the attacker knows the password to it.

thats what I'm trying to do; I can't see how to sweep OR import something that will create a spendable balance in this new wallet from the address I know has a balance.  The sweep button stays greyed out when I enter the armory private keys that were generated by armory.   there are two types,  privbase58 and privhexBE, I tried both, together and individually, with and without the privbase: prefixes and with and without the spaces between all of the characters in the key, with and without the address included and the sweep button still stays greyed out.  Thats most if not all of the possible permutations of entering this info.  What am I doing wrong?  I'm a btc newbie but pc literate and this is not going well.....

Sounds like a formatting issue. You need a "WIF" (wallet import format) private key. If armory only gives you the key in hex you can convert it using e.g. https://www.bitaddress.org/

1720  Bitcoin / Development & Technical Discussion / Re: How are referenced output scriptPubKey found in a very large blockchain on: April 29, 2016, 09:47:54 PM
Hi all

Imagine you made a tx that moves bitcoins that had been lying a very long time on the same address (let's say 10 years).
So in this tx, you have to reference this old transaction, which is done by declaring the hash of that tx (you can read that on the bitcoin wiki, topic: transaction).
To validate whether you have the right to claim those funds, the validating node has to retrieve the scriptPubKey of the referenced tx.
But how is this done? I wonder.
In 10 years the blockchain will have grown by over 1000GB (2MB Blocks assumed). So how does the validating node search for the referenced tx? Does it simply go backwards, searches every block? But how long would that take with 1000GB?

Sincerely

It keeps a record of all unspend transaction outputs (aka UTXO set).
